Patented July 22', 1813.

Application filed November 11, 1912. Serial No. 730,608.

To all 'wkcmitm concern:

Be it knownt at we, An'rnun A. DU- BUQUE and PHILIP H. Vorer, citizensof the United States, residing at Houston, in

ing is a specification.

Our invention relates to new improvements in pumps.

The invention consists in the. provision of a dish-like deflectorarranged within the head of the water box of the ordinary pump I whichis used in forcing water into the orthe rib 7 and the liner 111 onedirecti n. A space .is thus dinary oil or water well.

The object of the invention resldesm the provision of a deflector in apump of the character described which will rest egamfi the pump linerand hold the same in place and which will at the same time protect thehead of the water box against the direct force of the fluid pressure andwill thereby prevent leakage of fluid around the said head and will alsodirect the fluid in the proper directionand thus prevent the un 'necessary loss of any fluid pressure.

With the above and other objects in View, the invention has particularrelation to cerrain novel features of construction, and arrangement, anexample of which is given in this specification and illustrated in theaccompanying drawings, wherein- Figure 1 is a side'elevation of a pump,shown partially in section. Fig. 2 is a plan view of the deflector whichis arranged within the head of the water box. Fig. 3 is a sectional edgeView thereof. Fig. 4 is an end view of the water box with one of theheads removed. Fig. 5 isa plan view of a modified form of deflector, andFig. 6 is a sectional side elevation thereof.

Referring now more particularly to the drawings, the numeral 1 refers tothe water box of the pump which is provided with a suitable inlet 2 andoutlet 3. The valve casings are indicated by the numerals 4:, 4 and 5,5. The water box includes two cylindrical chambers, as 6, 6, arrangedside by side. Each chamber 6 has an annular rib 7 extending around theinner wall thereof and near the longitudinal center thereof. Within eachchamber 6 is a cylindrical liner 8 having an annular rib 9 around theperiphery thereof, the rib 9 resting against preventing the movement ofprovided around the liner. This space around one end of said liner isfilled with packing 10 which rests against the rib-9 l of the liner andis held in place bymeans of the county of Harris and State of Texas, Khave invented certain new and useful lmprovements in Pumps, of which thefollowa metallic ring 11 which surrounds the end of the liner and restsagainst said packing.

A head 12 is secured over the end of each chamber 6 by means of suitablebolts 13 and useful and between said head and water box is a packing 14which is provided to make the water box water tight. Within the liner 8,

the ordinary piston 15 reeiprocates, being driven by the-piston rod 16which in turn is driven back and forth by the engine 17.

The construction hereinbefore demribed is that of the ordinary and wellknown pump and no protection is sought thereon, the invention consistingof the improvement here inafter to be set forth.

The numeral 18 refers to a concave, dishlike metallic plate, of such asize as to fit snugly within the end of the chamber 6 and whose rimrests against the ring 11 and holds the same firmly in place against thepacking 10. The rim of the upper portion of the plate 18 has-beenflattened and thus does not contact with the liner and a pas sageway isthus provided for the fluid to pass from the liner 8 through thepassageway 19 and thence through the upper por tionof the water boxof'the discharge 3.

One -side of the plate 18 being flattened leaves a flat U-shaped rim 20which rests against the ring 11 and the lower portion and sides of theend of the liner 8. A set bolt 21 is threaded through the centralportion of the head 12 and its inner end rests against the plate 18 andholds the. same firmly against the ring 11' and the end of the liner 8and thus holds said ring and liner firmly in position and also securesthe packing 10 in place. As the piston 15 is driven forward, the fluidis forced against the concaved side of the plate 18 and by it isdeflected directly through the passageway 19. Were it not for the plate18, the head 12 would receive the full force of the impulse deliveredfrom the piston and the packing 114 kwould be displaced, thereby causinga It is the object of the plate 18 to hold the liner 8, the packing 10and the packing ring 11 in position, as well as to direct the fluidpressure and thus minimize the loss thereof. The plate 18 is providedwith a portion 21' Which fits into a corresponding groove 22 in the Wallof the chamber 6 and the plate is thus held in position and preventedfrom turning.

Figs. 5 and 6 show a modified form of the invention. This form consistsof the plate 18 in, which the rim 20 is extended and formed into acylindrical ring 23. In case this modified form is used, the packingring 11 may be dispensed with, inasmuch as sai clylindrical ring 23takes the placethereof, t e modified method consist-in in making said"ring 11 integral with the pflate 18. The upper side of ring 23 ispartially cutaway, forming an opening 24 through which the fluid isdischarged into-the passageway 19.

What we claim is '1. In a pump of the character described, a water boxand a cylindrical liner therein, a head secured over one end of saidwater box, a disk-like plate within said head and resting against saidliner, one side of which is spaced from the liner so as to allow a fluidpassageway between said plate and liner.

2. In a device of the character described, the combination with acylindrical water box, of a cylindrical liner secured therein, a headsecured over one end of said water box, a concaved plate within saidhead,,and partially closing one end of said liner, one side of saidplate being spaced from the liner to allow a fluid passageway betweensaid plate and liner.

3. A pum of the character described having a cylin rical chamber withashoulder around the inner wall thereof, a cylindrical liner having anannular rib around the periphery thereof, said rib of said liner rest:

ing against the shoulder of said chamber, a head secured over one end ofsaid chamber, a concaved, disk-like late arranged at the end of theliner, one e ge of said plate being spaced from the liner to provide afluid passageway between said plate and liner end and anadjustable meanscarried by the head and resting against said plate and holding .the samein position against said liner.

4. In a pump, a liner and a concaved, disk-like plate partially closingone end thereof and having one side thereof spaced from the liner.

5. In a pump, a liner, a concaved disklike plate, a rim extending aroundthe edge thereof which is elevated above the surface of the plate andhaving one side of said rim cut away, said plate being arranged at theend of the liner so as to partially close the end thereof.

6. In a pump of the character described, a water box and a linertherein, a head secured over one end of said water box, a plate withinsaid head and arranged to partially close one end of the liner, one sideof said plate being spaced from the liner so as to allow a fluidpassageway between said plate and liner.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
